Reflecting Intelligent Surfaces (RISs) have garnered considerable attention as a viable solution for wireless communication systems in recent years1. RISs operate by manipulating the phase and amplitude of incoming signals through precise adjustments in surface impedance2, 3. Moreover, RISs offer real-time dynamic changes in impedance and reflectivity, enabling various advantages for wireless communication systems such as enhanced spectral efficiency, expanded coverage, and reduced interference4. Several techniques are employed to achieve reconfigurability in RISs, including the utilization of Varactor Diodes5-7, PIN Diodes8, 9 and MEMS10.

Abstract
Reflecting Intelligent Surfaces (RISs) have garnered considerable attention as a viable solution for wireless communication systems in recent years1. RISs operate by manipulating the phase and amplitude of incoming signals through precise adjustments in surface impedance2, 3. Moreover, RISs offer real-time dynamic changes in impedance and reflectivity, enabling various advantages for wireless communication systems such as enhanced spectral efficiency, expanded coverage, and reduced interference4. Several techniques are employed to achieve reconfigurability in RISs, including the utilization of Varactor Diodes5-7, PIN Diodes8, 9 and MEMS10.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
